The pseudospin-electron model is formulated for the description of the correlated proton-electron charge transfer in the complex with hydrogen bonds. The energy spectrum of the model is obtained. The ground state diagram is ...

We suggest algorithms for calculating arbitrary order correlation functions (S₁i. . . Sinin)c and distribution functions (Si₁. . . Sinin) of a nonuniform Ising chain.

Using the dynamical proton (pseudospin)-heavy ion (lattice) model and the Green function formalism, the effective total differential cross sections for both coherent and incoherent neutron scattering are derived. The ...

A model of quantum particles performing D -dimensional anharmonic oscillations around their equilibrium positions which form the d -dimensional simple cubic lattice Zd is considered. The model undergoes a structural phase ...

The review of the theoretical study of the critical phonon scattering and anomalous heat transport near the phase transition temperature Tc is presented. An interpretation and quantitative approach to the description ...

Based on the direct domain observations in the Rochelle salt crystals, the final stages of polarization and the dependence of polarized state stability on the electric field strength E and on the electric pulse duration ...

We review some recent results on statistical mechanics of the one-dimensional spin-1/2 XY systems paying special attention to the dynamic and thermodynamic properties of the models with Dzyaloshinskii-Moriya interactio ...
